ONO, Calif. – The Shasta County Sheriff's Office has resumed its search for a missing 6-month-old baby with crews combing a sparsely populated area in Northern California.

The search for Ember Graham resumed Saturday after investigators cordoned off an area in Ono and sheriff's deputies kept an overnight watch.

Shasta County Sheriff Tom Bosenko tells the Record Searchlight (http://bit.ly/1Rqm0RI ) that new developments in the case led his investigators to the small town about 10 miles west of Happy Valley, where the girl disappeared from her father's home.

He says teams specializing in ground search and human tracking and cadaver dogs are scouring terrains for clues.

Detectives have named the baby's father, Matthew Ryan Graham, as a person of interest. No official charges have been filed against him.
